Another object is to provide a' heatingmeans by'which the mainbody of oil will be heated somewhat to rnaintainit at a proper viscosity and the oil adjacent the pump inlet will be maintained at a coii'siderablehig-her temperature so that atmosplie'ric changes'ol temperature will not change therate cf discharge from the'pumps. -Tliinvention consists in the improved construction'and combination of parts, to be more filly-described hereinafter, and the noveltyof which will be particularly pointed out and. distiniitlfelaimed.

ber 3, asby studs and nuts"! ii, are oppositely positioned parallel rows of pump casing or housings II, each having an outlet -or' discharge nipple l2 projectingupward-from the top'iace of closure member "3.; The pum p casin'gs each includes a laterally, downward andinward inclinedf ump cylinder I 3"which communicates with a vertical inlet and discharge passage I4 extending through casingl lj-flifit theinlet endof passage H! which openssubstant'iallyaii'th casing bottom wall, is a' strainer element" preferably a cylindrical screen of lfine wirerne'sh'clos'ed at its bottom end and carried by a nut I fiffwithin the passage [4 respectively below'and above the communication of the pump cylinder therewith, are valve means 11, preferably downward" seating ball checks. Within the cylinder [3 thereis'a pump plunger or piston I8 which projectsj'th' from at"a down ward inclination and which reciprocated by the drive mechanism (not shown) driven by shaft 5, 1 S8Cl1I8dtO" and suppgrted by the lower ends of the pump casings or members l 'there is ashield member leh vin' j 'hd izbiital top portion and a depending continuousrnarginal flange or skirt 20 which terminates below the 'planelof the inlet 0 Pa The nuts 16 serve also to clamp the shield member to the pumpfinlet members 2 l ,the shield mmber being apertured as at 22 (Fig. 3) torecelve the members! I Within the casing is aheating'means 2 3 whichispositioned beneath the shield member l9 andadjacent the pump passage inlettso' that a quantity of heated. fluid or lubricant will be maintained by the shield at the pump inlet for supply to passage l4. ,The means 23'preferabl'y comprises a steam conduit or tube having an anagram an outlet 25 which open through the rearwall of, the casing. The steam conduit 231s .of sinuous form lying in a plane adjacent and parallel to the bottom wall of the container I. 'Ihe conduit 23 has substantially parallel runs or portions 26 intermediate the bends or turns 2'! thereof, such that adjacent runs or portions 26 beneath shield memberll 9 extend along opposite sides of the row of pump casing inlet scr eens l5. f I v. v

The operation of the heating means is as follows: Steam or other heating fluid admitted at conduit inlet 24 will flow through the conduit Band from the outlet 25. {The heat of the steam or fluid will be imparted by the runs 26 and bends 21 to the oilin the'chamberl and particularly to the oil adjacent the pump inlets within screens Ii-"The heated 'oil tends to rise but will ,be caught by the-shield members l9 and be maintained or trapped at the pump inlets so thatthe "viscosity of the oil entering the pump passage I4 will be held substantially constant. It will also be noted that'the temperature of the oil beneath the shield members I9 will be main ,tained at 'azhigher 'temperaturethan .the remain ing' body of oil-rinichamber 2 due to the trapping '7 of the oil by the shields thereby increasing the i 1.
